This branch of the US Postal Service is located at "Five Corners", a two minute walk from the year-round Vineyard Haven ferry. With a large, free parking lot and a building shared with Cumberland Farms, it makes this branch a popular one. It sells shipping boxes/tubes (some decorate for birthdays/holidays, too), packing materials, postage scales, canvas totes and more.
Though it has a large number of postal boxes at this branch, the availability of a rental is sometimes a rare commodity. It stresses the importance of paying the rental fees on-time so customers don't "loose" their box, and therefore offer the means to pay the bill for it online.
